note to OAA, bubbly women make better narrators!
Yes! A video version featuring an attractive female pilot would probably make learning every subject soo much easier than just reading dry text.
Two weeks is not enough time to read and understand air law so you just haven't given yourself enough time! If I were you I would read the book, make whatever notes you feel you need to, then do practice exams from a question bank or from the confuser. I don't see any reason to book the exam in advance as this will only put you under pressure. There are no time limits for learning the individual PPL subjects, so only book the exams when you feel ready.
Good luck
